Specification of Letters Patent.

Application ledJ une 30, 1,914. Serial No. 848,233.

T0 all whom it may concern: Be it knownl that I, THOMAS J. BROWN, a citizen of the United States, residing at Crestwood, in the county of Oldham and State of Kentucky, have invented certain new and useful Improvements in' Envelpps; and I. do hereby declare the following to be a full, clear, and exact description Of the invention, such `as will enable Others skilled in the art to which it appertains to make and use the same.

- This invention relates tO envelops, and

'more particularly to that type generally i known as the. Outlook in which is proobjection to the ordinary type of envelop of vided a section of transparent paper or other material covering an opening in the front of the envelop whereby the heading of the letter, bill Or other inclosure is visible. The

this character is that except by very accurately folding and tting the letter or other inclosure within the envelop and placing the heading on the inclosure at a certain point, the inclosure is liable to move to a position wherethe heading thereof is not visible through the transparent section, and thus considerable time Of the postal clerks is lost in adjusting the inclosures of the envelops to make the address visible.l

`Figure 1 represents a plan View of the enn velop, showing the iap in extended position. Fig. 2 represents a plan view of the envelop, showing the flap closed and sealed. Fig. 3 represents an enlarged detail sectional vview on the line 3-3 of Fi 2.

Referring to the drawing 1n detail, wherein similar reference numeralsdesignate corresponding parts throu hout the several views, the numeral 5 indicates the front Of the envelop having one of its ends suitably nshaped to provide a iap 6 and having the Opposite end portion doubled upon itself to provide the vback or rear wall 7. In the Ordinary envelop of this character provided with thev transparent section of material, the Opening in the body of the envelop is formed .in the' front thereof, whereas I provide the Opening, designated by the numeral 8, in the back 7 of the envelop, whereby the position Of the contents Of the envelop are visible while the flap 6 is-being sealed. The usual transparent material 9 is secured over the opening 8 and against the inner face 'Of' the back 7.

The back 7 is secured at its ends to the body or front 5, and the -ap 6 is adapted to be folded on the dotted line 10. An Opening 11 is formed in the back 7 of the envelop and is adapted to receive the tongue 12 formed in the gummed end portion 1.3 of the Hap 6. While I have here shownvthe tongue 12 Of tapered formation, it will be understood that the size and shape thereof may be varied as desired, or to meet various requirements.

In use, the inclosure 14 bearing the address Of the addressee is positioned within` the envelop in proper `position behind the section Of transparent material 9. The flap 6 of the envelop is subsequently folded and sealed in thevusual manner, thus simultaneously securing the flap 6 to the back 7 and securing the inclosure in proper position behind the material 9.

What I claim is: L

An envelop includingl a back having large andsmall openings therein, a transparent covering for said large opening, a flap having the marginal portion gummed, and a tongue struck out from the gummed portion of said flap lying entirely within the edge of the latter and adapted to overlie and eX- tend through said small Opening when said Hap is closed and secure the contents of the envelop in .adjusted position behind said transparent covering. A

In testimony whereof I aflix my signature in presence'of two witnesses.

THOMAS J. BROWN.
